Question

You have 60 CD cases that you would like to store on a shelf that is 24 inches long. if each CD case is 3/8 inch wide, is there enough room on the shelf for the CD cases? Explain why or why not.

Answer 1

Yes you do.

The shelf is 24 in. long, so to fit, the total width of all the cases must be < 24 in.

If each case is 3/8 inches:
60 * 3/8 = 22.5

22.5 < 24, therefore they will all fit.

Answer 2

Answer:

There is enough room on the shelf for CD cases.

Step-by-step explanation:

Consider the provided information,

You have 60 CD cases and each CD case is 3/8 inch wide.

It is given that the shelf is 24 inches long,

Let us find how much room on shelf 60 CD covers,

$60\times \frac{3}{8}$

$7.5\times 3$

$22.5$

60 CDs cases requires 22.5 inches room on shelf. Whereas the length of the shelf is 24 inches.

As 24 is greater than 22.5, Thus we can say that there is enough room on the shelf for CD cases.
